Am new to Tableau, My task is to take a report by joining mongodb data with mysql data. When i looking for the solution i found that in tableau i can do that. I connect a mongodb to tableau using quasar api and Web Data Connector(an option in tableau). Now i can fetch data from mongodb in tableau but when i attempt to join with mysql table even though there are data in both table i can't see any result.

I want to join storeid from mongodb to storeid in Mysql table. The datatype of storeid in Mysql table is BIGINT. That is why i gave tableau.dataTypeEnum.float dataType to storeid web data connector schema.
